EDWARD A. STIGGINS, OF BEVERLY, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE LIACEINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed April 22. 1911.

1 b all whom it may concern:

Be it known that I, Enwano A. Srreorns, a citizen of the United States, residing at Beverly, in the county of. Essex and State of Massachusetts, have invented certain Improvements in lVork-Supports, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to work supports for shoe machines and is herein shown as embodied in a work support or a jack designed particularly with reference to holding a last and the parts of a shoe in position forthe performance thereon of the operation of heel seat lasting by a machine of the hand method type. It is to be understood, however, that mechanism involving the invention is by no means limited to such use, but may be applied to jacks for holding shoes in proper position to be operated upon by various machines for treating the heel or the heel-seat portion of the shoe, such, for example, as slugging machines, nailing machines, trimming breasting machines, and the like.

In lasting the heel-seats of shoes upon machines of the hand method type it is the present general practice for the operator to hold the shoe in his hands with its bottom against a downwardly projecting rest and with the side of the heel portion pressed laterally against a rest which is wide enough to form a firm abutment. The work being so held, the machine acts to wipe in the upper material, which includes the flange of a molded or unmclded heel stiffener, and to drive a tack through it and the insole, clenching the same upon the nail plate of the last. \Vhen this cycle of operations is completed, the operator slides the shoe along the edge rest at the same time rotating it an amount corresponding to'the curvature of the portion being acted upon, and the operation of wiping in and tacking is repeated by the machine. In\this procedure, the spacing of the tacks from the edge of the last is determined by the position of the edge rest relatively to the driver, while the spacing between the tacks is determined en v Specification of Letters Patent.

tirely by the judgment and skill of the operator.

An object of the present invention is to hold a shoe securely and present the same in proper relation to a wiping and tacking mechanism, so that the tacks will be properly located about the heel-seat independently of the usual edge rest or of any great skill or attention on the part of the operator, the operation required being merely the placing of the shoe upon the jack spindle, the raising of it into position, and the swinging of the shoe slowly about the jack spindle through a portion of a revolution, the mechanism provided acting to locate the heel-seat properly beneath the wiping and driving mechanism and to so guide itsmovement relatively thereto that the tacks will be driven along a predetermined path which, in theform of the invention shown and described, is substantially in the form of a portion of an ellipse and corresponds very closely to the outline of the heel or heel-seat of an ordinary shoe. The operator has only to rotate the shoe by slight intermittent movements about the last pin after each cycle of operations of the machine in order to space the tacks properly from each other, this movement requiring no particular skill or attention on the part of the operator. v

An important feature of the invention relates to the means employed for securing a movement of the shoe support such that a relatively stationary operating mechanism or tool will trace a predetermined path rela tively to the heel or heel-seat of a shoe carried by said support. In the construction shown and later to .be described in detail, this path is elliptical in form and the movement of the shoe support is effected by mounting the shoe support for movement upon a relatively stationary carrier and providing, between the support and the carrier, mechanism such that when the support is given a rotative movement relatively. to the carrier a point on the heel or heel-seat of the shoe on the support will tracean elliptical path relatively to a stationary point. The mechanism provided for this purpose involves broadly the principle of the well-known trammel for drawing ellipses, slots at right angles to each other being formed in the parts of the carrier and a member corresponding to the pencil-carrying arm of the trammel being provided with pins at one end engaging the slots through sliding blocks and having its other end fixed to a portion of the carrier which is stationary relatively to the shoe support. The fixed end is, however, arranged for adjustment for changing the size of the ellipse generated by a point on the heel-seat and means is provided for adjusting the position of the pins relatively to each other in order that the ellipticity of the movement given to the shoe may be varied. lVhen the pins are in line with each other, the movement will be circular, and as they are displaced more and more out of line, the path of movement becomes elliptical with an increasing degree of eccentricity.

Another feature of the present invention is embodied in the means for raising the jack carrier upwardly and at the same time forcing it backwardly to position the shoe properly beneath the operating devices and in the means for locking the carrier and jack in place when this position is reached. For effecting the vertical movement, a segment gear journaled on the carrier is provided which meshes with a rack pivoted at its lower end to a part stationary on the base of the machine, and a second segment gear also journaled on the carrier meshes with the segment gear first mentioned and is provided with a hand lever for rotating it to cause the first mentioned. segment gear to climb the rack and elevate the carrier. The rearward, or oscillating, movement of the jack carrier which takes place simultaneously with its upward movement is effected by inclined guiding slots formed in the carrier and engaging projections on the relatively stationary base. For effecting the locking of the jack in its raised position, the segments are provided with smooth or untoothed portions, one concave and the other convex, which interengage as soon as the jack is raised to the proper height and lock the same in raised position until the hand lever is again operated.

Another important feature of the invention involves the mechanism for closing the shoe clasp or heel band upon the shoe and for effecting this operation simultaneously. with the movement of the jack into raised position. From the toothed segment ahox e reierred to, which is provided with a hand lever, motion is communicated by suitable mechanism to the heel band to force the same forwardly against the back of the heel portion of the shoe. As pressure is applied by the heel band to the back of the shoe, the forward portion of the heel band, which is connected through the mechanism referred to with the hand operated segment, tends to meaeeo move inward against the shoe and this inward motion is communicated through suitable mechanism to the end of the heel band at the opposite side of the shoe so that both sides are pressed in against the heel portion simultaneously.

Another feature of the invention is embodied in means for giving the ack a slight movement or sensitive adjustment toward and from the machine independently of the movements described. This consists of a shaft mounted in a stationary portion of the jack base and carrying an eccentrically mounted pin arranged to communicate its movement to the jack carrier so that rotation of the shaft will move the jack slightly in and out to position the heel-seat accurately with respect to the tacking mechanism.

As another feature of the invention, the last pin is mounted for movement laterally of the longitudinal axis of the lastcarried thereby so as to permit the shoe clasp or heel band, as it closes, to center the heelseat of the last relatively to the heel band and to the mechanism for operating upon the heel-seat. As disclosed, this result is effected by mounting the last pin upon a block which is pivoted to the jack base at a point to the rear of the last pin.

Another feature of my invention is involved in the manner of mounting the toe rest for adjustment relatively to the last pin for effecting a vertical movement of the toe rest simultaneously with its adjustment longitudinally of its support. This result is effected by arranging the member along which the support of the toe rest slides at an obtuse angle to the axis of the last pin, so that as the toe rest is moved nearer to the last pin to accommodate smaller shoes it will, at the sametime, be raised vertically to [compensate for the diminished thickness of the toe portion of the smaller shoe.

The foregoing and other features of the invention will appear more fully from the following description and drawings, in

which loo Figure 1 is a perspective view of an illusening the heel band about the heel and producing elliptical movement of the heel-seat; Fig. 4 is a plan view of the heel band and its closing mechanism; Fig. 5 is a detail of a portion of Fig. 3. Fig. 6 is a fragmentary detail of the fine adjustment mechanism.

Referring to Fig.- 1, the character 2 indicates a base which, for convenience, is made ing machine by a collar 4 (Fig. 2} and .clamping screws 6. When the clamping screws 6 are loosened, the lower end of the H base 2 may be adjusted toward and from the pedestal by means of a screw 5 and the screws 6 then set up to hold the base in fixed position. Pivoted to the bottom of the base 2 by a bolt 8 is a. rod 10 having a rack 11, Fig. 2, formed on its front side. Upon this rod slides a hollow standard 12 which forms the lower part of what may be termed the jack carrier, as distinguishedfrom the jack proper which supports the shoe and is turned with it. On the rod below the standard is a washer 14 of suitable material to act as a buffer and the weight of the jack is partially counterbalanced by a spring 16 fast at one end to a screw 17 on the base 2 and at the other end to a pin 18 secured to the standard 12 Journaled in bosses 20 extending forwardly from the standard 12 is a toothed segment 22 which meshes with the rack 11 on the rod 10. On the jack carrier above the bosses 20 are bosses 24 in which is journaled a toothed segment 26 which meshes with the segment 22. The segment 26 is provided with an untoothed or smooth face30 which, after the toothed portion has ceased to engage with the toothed portion of the segment 22, interengages with a smooth concave face 28 on the segment 22 and automatically looks it against further rotation. The journal of the segment 26 is extended to the left and provided with I an operating lever 32. A portion of the jack carrier integral with the boss 24 extends upwardly at an angle to the vertical and is provided with an oblique guiding slot 34.. A plate 36 is bolted to the base and carries a stud shaft 38 having at one end a handle 40 and at the other a pin eccentrically at-' tached thereto and engaging a slide 31 mounted in the slot 34 of the jack carrier.

The operation of the device as thus far described is as follows: Movement of the hand lever 32 turns the segment 26 and hence the segment 22 which, being in engagement with the rack 11, causes the segment 22 to climb the rack and raise the jack carrier upon the rod 10, this movement being assisted by the spring 16 until the smooth faces 28 and 30 engage and the jack carrier is automatically locked in raised pojack sition. Meantime the portion of the carrier having the oblique guiding slot 34 moves over the slide 31 and the jack carrier as a whole is oscillated about the pivot 8 and forced backwardly toward the lasting machine, this movement being due to the inclination of the slot. -A finer adjustment of the jack toward and from the machine (see Figs. 1 and 6) may be effected by manipula-' the slide 31, gives the jack carrier and jack a slight oscillatory movement about the pivot 8 to furnish a fine adjustment for the work backward and forward under the lasting mechanism.

Above the portion of the jack carrier. in which the inclined slot 34 is formed is a jack seat portion 42 having at its rear end an upstanding portion 44. Upon the portion 42 is seated the lower plate 50 of the jack proper. A shaft 46, Fig. 3, passes through a sleeve 48 stationary with the plate 50 and carries a pinion 52 fixed upon it. For assembling the pinion 52 in its socket in the plate 50 the groove 200 is made larger than is necessary, and after the pinion is in place is partially filled by a strip 53 secured therein which serves to ,hold the pinion in assembled position. The pinion 52 meshes with the rack 54 on a bar 56 and is actuated by rotation of the shaft 46 as follows: A pin 58 fixed in the shaft 46 projects through a horizontal slot 60 in the sleeve'48, Fig. 5, and engages the inclined slot 62 in-the sleeve 64, Fig. 3. The sleeve 64 is splined on the sleeve 48 which is fast on the plate 50. By this means the sleeve 64'is prevented from I rotating and when given longitudinal movement the action of the inclined slot upon the pin 58 is to rotate the shaft 46 and pinion 52. An outer sleeve 66 is secured by a screw 67 upon the sleeve 64 and is connected by a bar 68 and ball and socket joints '70 and 72 with one arm 74 of a bellcrank lever which is fulcrumed in bosses 76 on the standard 12. The other arm 78 of the bell-crank is connected by a link 80 with a wrist pin 82 on the segment 26. From an inspection of Fig. 3 it will now be clear that upon rotation of the segment 26 in a counter-clockwise direction, as indicated by the arrow,to raise and lock the jack the bell crank will be operated to pull down on the connecting bar 68 and the sleeves 66 and 64 whereby the pinion 52 is rotated in a toothed portion 94 which engages a toothedsegment 96 on one arm of a lever 97 fulcrumed at 98 on a bracket 100, Fig. 1, of the member 88. The upper portion 102 of the lever is substantially semi-cylindrical and extends around to a bracket'lO-Jl, corresponding to the bracket 100, in which it has a fulcrum corresponding to that at98. A shoe clasp or heel band 110 is attached at the middle of its bent portion by a flexible connection 101, Fig. 4, to the semi-cylindrical portion 102 of the lever 97 and is, by movement of the rack bars, pinions and lever described, pressed against the heel of a shoe, the heel portion of the last of which is sup ported upon a spindle 105 and the toe portion upon a vertically and horizontally adjustable toe rest 107, Fig. 1. The forcing of the heel band closely against the side of the heel portion of the shoe is accomplished by further movement of the lever 97 in the same direction. A lever 103 is pivoted to the lever 97 at 106 and to one end of the heel band at 108. It will now berapparent that, as the rear portion of the heel band is held practically stationary by its contact with the shoe, movement of the lever 97 forward will tend to rock the lever 103 on its pivot 106 and force the end 110, Fig. 1, of the heel band toward the' shoe. This motion should, of course. be communicated to the corresponding end of the heel band on the other side of the shoe. This is accomplished by the mechanism shown in Fig. 4. The lever 103 carries a segment rack 112 which meshes with a segment pinion 114 engaging a similar segment pinion 116. The segment pinion 116 in turn engages a toothed segment 118 on a lever 120 corresponding to the lever 103. In this way it will be apparent that the two ends of the heel band are made to move simultaneously inward to the same extent and thereby closely embrace the heel portion of the shoe. The means for giving a point on the heel seat of the jacked shoe an elliptical movement comprises the slot 200, Fig. 3, in the base 50 and aslot 202 at right angles to it. These slots are slidingly engaged respectively by blocks 206, 208, pivoted on opposite sides of a block 210 by pins 205, 207 respectively. The end of the block 210 is seated in the upstanding portion 44 of the jack carrier 42, and is provided with slots 217 having about their upper peripheries shoulders 219 which engage the heads of screws 216 for holding the block 210 against upward displacement and permitting lo ngi tudinal adjustment of the block and the jack relatively to the support 42. In order that the ellipticity of the movement of the heel may be varied, the block 206 instead of being pivoted directly to the block 210 is pivoted to a slide 212 adjustable longitudinally in a dove-tailed slot 214 and normally held in place by a screw215. are rigidly secured together by screws passing through holes 201 in the plate 50 into threaded holes (not shown) in the plate 88, the plate 210 having free movement with respect to the plates 50 and 88 except as restricted by the blocks 206, 208 in the slots 200 and 202, respectively. I

The elliptical movement produced by the The plates 50-and 88 mechanism just described will perhaps be best understood if it is considered first What will take place if the block 210 is free to move while the plates 50 and 88 are held stationary. Suppose a point is taken on the slotted end of the plate 210 and the plate is swung around over a stationary plane, all the other jack parts being stationary, it will be apparent that the action of the pins 205, 207, the blocks 206, 208 and the slots 200 and 202 at right angles to each other Will be to constrain the point to trace an ellipse upon the stationary plane, the action being similar to that of the ordinary ellipsograph or trammel for drawing ellipses. If now we hold the plate 210 stationary, as it is in practice, being clamped by screws 216 which pass through slots 217 into the upstanding portion 44, and move the plates 50 and 88 with the ack thereon it will be seen that a stationary point, for instance, the driver of the lasting machine, will trace an ellipse upon a plane supported on the jack and swung around with it, or upon the heel-seat of a shoe held by the last pin 105 and the heel band 110.

. The shoe is supported upon the jack by a spindle 105, Fig. 1, and a toe rest 107, the

spindle is attached to a block 122 which is pivoted by a' screw 124 to a slide 126 in which is threaded a screw 128 having a thumb nut 130 and ournaled in a plate 132. By this means the shoe may be adjusted to and from the heel band and is permitted by movement of the block 122 about its pivot 124 to center itself therein. The toe rest slides upon a member 134 which is bolted to the ack member 50 and serves as a lever for turning the shoe beneath the heel-seat lasting mechanism indicated at A, Fig. 1. The toe rest is vertically adjustable by means of a screw 136 splined to a stem 138 and threaded through a thumb nut 140.

It will be observed from Fig. 2 that the member 134 upon which the toe rest is mounted for sliding adjustment is inclined downwardly and makes an obtuse angle with the last pin so that as the toe" rest is moved nearer the last pin to accommodate a smaller shoe it will be raised, due to the inclination of the member 134, and is thus automatically adjusted vertically to compensate for the diminished thickness of the toe portion of the smaller shoe. Accordingly, only the finer adjustments have to be taken care of by the thumb nut 140 and screw 136.

The operation of the device as a whole may now be briefly reviewed. The operator places the last carrying the assembled 1nsole and upper upon the spindle 105 and rests the toe of the shoe upon the rest 107. He then depresses the lever 32 which first, through the rack 11 and segments 22 and 26, raises the jack and shoe toward the lasting devices at A, Fig. 1. At the same time the inclined slot 34 carries the shoe back under the lasting devices. After reaching the limit of vertical and lateral movement due to the instrumentalities noted. the smooth portions 28 and 30 of the segments interengage and the jack is locked in position. Should some slight further movement be necessary, due, for instance, to the varying characteristics of individual shoes, the lever 40 may be manipulated to give a slight toand-fro movement to the jack.

During the upward movement of the jack and after the segment 22 becomes locked, motion is transmitted from the segment 26 through the link 80, bell crank 7 4, bar 68 to the sleeves (36, 64 to move them downwardly and by means of the pin 58 and slot 62 this motion is transmitted into rotary motion of the shaft 46 and pinion 52. Thence through rack 84, pinion 86 and rack 92 the lever 97 is oscillated .and the heel band clamped about the heel asdescribed. The shoe is now firmly held in proper position beneath the lasting device. The shoe is first swung around (say to the left) to bring one end of the heel band adjacent to the lasting mechanism and the lastingmachine started. The tack block 220 wipes a portion of the upper in over the heel-seat and the driver 222 drives a tack through it to tack it down tetween this cycle of operations of the lasting machine and the next, while the tack block is withdrawn, the shoe is swung slightly to the right to present a new portion of the upper to the wiping action-of the tack block and to enable the tacking mechanism to drive another tack somewhat displaced from the first along the peripheryof the heel-seat or heel. As the operation proceeds, the tacks are driven along an elliptical path, (due to the elliptical movement described). The shape of the heelseat of a shoe approximates so closely to a portion-.of an ellipse that by giving the heelseat a truly elliptical motion beneath the tack driver the tacks are arranged at a substantially constant distance from the edge of the heel about the heel-seat. By this deice, a comparatively unskilled workman may accurately perform the operation of heel-seat lasting, it being only necessary for him to set the shoe upon the jack, operate the lever (and possibly lever 40), start the machine and swing the shoe around with what is substantially a continuous motion, interrupted only by the brief dwells of the tack block and driving mechanism upon the shoe.
